I just finished drilling the beetroot as the rain started this evening. The first rain on dusty dry ground is an amazing smell, like the earth coming back to life. Before the rain, low dark clouds moved in and a ferocious wind whipped up clouds of dust from the field. It’s terribly dry. Hasn’t rained here for what feels like months; certainly for weeks. Every day, I look up the weather forecast on the internet and see a row of big fat sunshines for the next twenty four hours; next five days. Sometimes there’s rain forecast on day four or five, but it’s like tomorrow; it never arrives, always just out of reach, always in just a few days’ time.
So we’ve been thinking about water quite a lot. Before Easter, we brought down all the big black irrigation pipes from Sunny Acres. They are light weight, but long and awkward and it took Sebastian and Robert and several helpers half a day to bring them all down. Then Henning initiated Duncan in to the mysteries of the Sunny Acres irrigation system. It was one of Henning’s projects last year, finally set up and working, after delays and tribulations, just in time for the late planting of the leeks in July and then the unusually wet August. He never quite finished it how he wanted it, though, so all the pipes had to come back down to the garden to be fitted out with new couplings, which does make it much easier to clip them together and take them apart again. Then on Good Friday, as part of the traditional morning of common work, Henning and Sebastian and Robert and Bob took all the pipes back up to Sunny Acres and got the whole system working again.
This is how it works. Underneath the farm yard in a big concrete tank. All the runoff water from the farm yard collects in to that tank, so it gradually fills with a rich black brew of rain water mixed with a sort of slurry from the yard, the water from washing down the dairy, and the poisonous looking stuff that seeps out of the bottoms of the muck heaps. That black water can then be pumped up the track to a man hole by Sunny Acres. There, we connect one of the big black pipes, run it all the way along the bottom of the field, and link it up to a set of three sprinklers. Henning made a filter that sits in the pipe just before the sprinklers, so they don’t get clogged up with slurry, and the pump works on a timer so it can be switched on for half an hour, an hour or two hours. All pretty straight forward really, and a great way of catching and storing some of the water and nutrients from the farm yard and applying them where we need them in dry weather.
After getting thoroughly splattered with stinking black slurry water, Henning got the sprinklers going and had them running for several hours. I wasn’t too sure about spraying all this stinky water on the onions, but under the combined circumstances of drought and an underground tank of slurry overflowing in to the ditch to the stream, it seemed like a pretty good option. The first time I moved the sprinklers to set them up on a new patch I had a terrible battle sloshing and slipping about in smelly sludgy mud where the sprinklers had leaked, panicking as the water surged out of the pipes when I disconnected the sprinklers, and then struggling to heave around suddenly not-so-lightweight pipes now filled with litres and litres of water. I learned quite fast though, that it’s best to disconnect the pipes as close to the tap as possible, and so that the spare water gushes on the the grass rather than the bare soil of the field. Moving the pipes is one of those jobs that for one person takes an hour of struggle, sweat, and possibly swearing, whereas with two people it’s twenty minutes of quite simple and sensible work.
So good so far. But then on Easter Sunday the sprinklers stopped going round, and each only poured a gentle trickle of water on to its neighbouring cabbage. After a good deal of running up and down between pumps, taps, and sprinklers, in between consulting with Henning who was tied to his office in the house, it appeared that the problem was not in the sprinklers, or the pipes, but either in the pumps or the tanks. Further investigations by William, Sebastian and Henning after Easter revealed that the water level in the tank might be too low, or perhaps that the tank is full with sludge and slurry rather than water. Which rather surprised us all because we thought the tank was unimaginably enormous and effectively bottomless when it comes to doing a bit of watering in Sunny Acres. So now rather than worrying about how to stop the tank overflowing in to the ditch, we’re working on ideas to make it fill up quicker. It’s quite fascinating to piece together a map of the network of drains and pipes and tanks under the concrete of the farm yard. No one (except possibly Markus) knows exactly how it all links up and what goes where. But today Stefan blocked up one underground pipe that should now divert the rainwater collected off the barn roof in to the tank under the yard, rather than straight to the ditch. And Henning has devised a cunning plan to collect the trickle of water running off the field from the land drains which now requires some lucky people to spend a morning digging a barrel in to the mud of the ditch.
As that thread of the water and irrigation story unfolds, we’ve also been using gallons and gallons of mains drinking water to irrigate the greenhouses and polytunnels, which seems close to criminal, but is currently the only option (other than letting everything wilt and die). We use main drinking water, too, to water in the lettuces and celeriac and kohl rabi and brussel sprouts newly planted out in to the dusty of Sunny Acres. That took Duncan a morning just to get all the hosepipes wheeled up to the field and connected across all the beds from the tap in the far corner by the water meadows. And then several more hours for Owen or Duncan or Sarah standing by each plant in turn, soaking it, moving to the next one, soaking it, moving to the next one… Hosepipes, I am sure, have some special magic that means they get tangled and twisted and knotted up even when they are lying still in what should have been a nice neat coil on the side of the grass. So then every time you might want to start using one, or move one, it takes half an hour just to untangle the thing before you even start with the watering.
Our other criminal use of precious mains drinking water is with the ingeniously clever watering tractor. It’s a sprinkler in the shape of a tractor, that can slowly propel itself along a bed, guided by the hosepipe paid down in front of it. It’s entirely powered by the flow of water through the mechanism inside, and can more or less be left to get on with the job. Earlier this week it developed a leak, though, which makes the whole thing fail; where it leaks under the tractor, the soil turns to mud and the tractor effectively does slow motion wheel spin, gets stuck and becomes a stationary sprinkler. Fortunately John, the multitalented bicycle repair man now graduated to tractor maintenance man, fixed the leak for me, and now the little watering tractor is back in action again.
So that’s a lot of stuff about watering and water, which is now finally bucketing down out of the sky. Hurrah.
Apart from messing around with water and irrigation, in the nearly a month since I last wrote, I’ve also been planting tomatoes, going on holiday, having my birthday, harrowing and ridging potatoes, hunting Easter eggs, sowing Easter grass, drilling leeks, making ridges for carrots and parsnips, ordering chicken food, not quite getting sunburnt, and digging up biodynamic preparations. Not quite in that order.
